Appiicafio'n mea January 22, 1912. serial No. 672,922.

To ill whom it may concemr Be itknown that. I, ROBERT W. ROSE- nRoUoH, acitizenof the United States, re-

` siding at Portland, in the county of Multnd mah and State of Oregon,have invented certain new and. useful Improvements in `Angle-Tracks; andI do hereby declare the followingto' be a full, clear, and eXactdescription of the invention, such as vvill enable others skilled in theart to which it appertains to make and use the same.

This invention relates to angle tracks and has for an object to providea track especially adapted for use vin angletrucks similar to thatdisclosed in my copending apl plication Serial No. 12,1911, i c

A further object of the invention isto provide a track especiallyadapted foruse in connection with cable drawn ca rs and presentingnewand improved features for 665,261 filed December carrying the cableand preventing the same'y from wearing t-he supporting ties..

IVit-h these and other objects in view the invention comprises certainnovel constructions, combinations and arrangement of parts as will behereinafter more, t'ullydescribed andv claimed.

In the drawings Figure 1 is a transverse sectional view of the improvedtrack showing a cable. carrying roller of hour-glass shape. Fig. 2 is aview similar to Fig. 1 showing a cylindrical cable-carrying roller. Fig.3 is a view of one of the cross ties showing one of the wear .plates inposition. Fig. -It is a top plan view of one of the cross ties with a'wear plate thereon and one of the supporting rollers adjacent' thereto,showing other cross tics without. supporting roll-A ers adjacent. Fig. 5iswan inverted plan view of one ot' the cross tics showing astrcngtluning plat/e ouille bottom. Fig. G is a top plan view of a curveshowing rollers for supporting the cable while passing about the curve.Fig. 7 is a transverse view ot' the track showing the position of aroller on a curve.

Like characters of reference indicate corresponding'parts throughout.the 'several views. v

It is well known that. where a car is drawn by a cable running above thesurface of the track it engages upon certain parts olE the track andcauses wear both ot' the track and the cable. 'lo prevent such unduewear the track comprising the rails 10 is provided with a cross ltie 11tapered from-jj the opposite en s toward the,nddle'so` thatthe middle isnarrower as indicated particularly'at Fig. 3..' The tapering of the tieto accommodate the angle truck formilgy Pen the subject'rnatter Aoitthe'aforesaid cooFF'IoE- ROBERT -w. RosEBRUGH, orvPoR'rLAND, OREGON.

ing application weakens the tie at the middle Y p oint, as is obvious,and to strengthen such tie and also to prevent Wear'of the cable uponthe tie a plate 12 is provided witlr'ar..

second plate 13 preferably of metal upon the under side of the tie sothat the tie sits l upon the mud sill-13 covering the under- 'plate 14.The tie is preferably provided at the oppositeends with shoulders orexten-` sions 15 by which such tie is :secured to the mud sill 14 byordinary spikesA 16.

Between certain of the ties 11, `as maybe found necessary, othershorter'mud sills 17 are embedded, carrying bearings 18 upon which arejournaled rollers 19 or 20, the.V roller l19 being lsubstantiallycylindrical, while the roller 20 is tapered from opposite ends towardthe middle to form the middle with a waist.. The rollers are notprovidedi at each of the cross ties but are spaced` alongV as the natureof the trac may make necessary or desirable and under normal conditionssupport the cable `without engaging against the ties. When the cable isslackened for any reason it will occasionally engage the top of one ofthe ties intervening between the rollers and forsnch purpose the plates12' are provided.

vFor rounding a curve, as shown at Fig. 6, the rollers 21 are set uponangle blocks 22 which-are secured to the mud sills 17, such angle blocksholding the rollers 21 at an inclination .to carry the cable as itpasses around such curve.- It Will be neccssaryor desirable to employ agreater' number of such rollers about the curvey than under ordinaryconditions and it maybe found desii-able to use one at each of the crossties 11, as shown at Fig. 6.

I claim:- i

l. In a railway track. cross ties tapered downwardly.from oppositeendstoward the middle, and means at the center of the ties forstrengthening the ties and wear of the cable on such ties.

2. In a railway track, cross ties tapered downwardly from the oppositeends toward the middleylneans at the middle of the ties forstrengthening the tics and prevent-ing wear of a cable on the ties, andaroller preventing- `the midle of the ties jou'emled adjacent ey cableout of uleptel normally support engagement with such weer means.
